Oppose electricity-stealing etc. in work, often to measure the voltage of electric power meter, be now switched on metering device and measuring equipment
Seal and table cover and protector, these undoubtedly considerably increase the triviality and difficulty of live work about electric power, even more important
It is：Oppose electricity-stealing at the scene and the boundary for screening responsibility is difficult to when collecting evidence, cause stealing evidence that court cannot be allowed to accept and believe, row of breaking laws and commit crime
For that cannot punish.
For another example, low-voltage distributing line is the insulated conductor for using, it is often necessary to measure the voltage between insulated conductor, in order to avoid
Because live wire and zero line make a mistake and caused by major accident, or cause the non-normal use of electric power because voltage swing is unknown.But
It is that the voltage that current voltmeter wants to measure insulated conductor is impossible.
For another example, in power science research, it is often necessary to measure the voltage between insulated electric conductor, it is often necessary to by instrument instrument
Table measures voltage value to determine electrical power, electric work, (maximum) requirement, electric flux etc., current power measurement technical merit
Do not accomplish " voltage is measured between insulated electric conductor ".
For another example, the measurement of voltage is always the blind area of power engineering measurement, current electric power between power cable inner lead
E measurement technology level is too far behind to catch up.
The present invention is fully achieved in insulated electric conductor by " the voltage measurement miniature probe being made using carbon nanomaterial "
